System Programs and Application Programs

Category : 5th Class

*     System Programs and Application Programs

 

 

There are basically two types of programs that we use: system programs and application programs. The system programs constitute what we call an operating system.  

 

*    The programs that make up the operating system are:

  • Control programs
  • Supervisory programs
  • Service programs

The control programs control and manage all the hardware and memory resources of the computer. They regulate and time the activities of the CPU and allocate memory space when it is required. They schedule the data to be received or sent through input and output devices. The service programs provide many services to the user. The most common example is the set of programs that let you save files and load them from floppies or CDs and copy, rename, delete files or folders. The Windows operating system has a few application programs associated with it. In the smaller classes, you may have used the one called Notepad for writing text. Examples of other application programs are word processor, spreadsheet and Internet Explorer.
